This invention relates to automatic guns provide such guns with a cocking and load-- ing lever under the" control of the gunner for reproducing manually the movements of the barrel and the gun mechanlsm which occur fective cartridge and cock and reload the gun.

In uns situated as described above,'.we,

accor ing to this invention,'provide in conmounted in or on one of the wings of an erates upon the coc junction with each gun an operating handle within reach of the gunner and a connection between this handle and the cocking and'loading lever on the gun. In the case of a gun aeroplane, this connectioh may be in the form of a transverse shaft o'ne'end of which isconnected to the ,said handle (arranged in or close to the cock-pit and the other end 01) and loading lever of the gun. Alternative and links may be used. I

In orderthat the said invention may be clearly understood and readily carried into eflect, the same will now be described more fully with reference to the accompanying drawings, in which Figure 1 is aadiagrammatic perspective view showingan automatic gun which is mounted on the win of an aeroplane and has its cocking and loa ing lever operated from a distance by mechanism includinga transverse shaft, and a r Figure 2 is a view similar to Figure l'showing a system of levers and links replacing the transverse shaft.

'In both of the figures A is the mechanism casing of an automatic gun mounted on an aeroplane wing which is shown by chain lines at A the framework of the fuselage being represented b chain lines at A and the cockpit at A. 1% represents the cocking and loading lever for co-operating with the crank handle A of the gun as aforesaid. This lever which is pivoted at B to the mechanism casing A, is shown as being of the Hyland type described in the specification of British y a system oi levers Patent o. 126,670. In the examples shown this lever B) is associated-with an auxiliary lever C as is described in the specification of our patent application filed concurrently herewith, this auxiliary leverbeing' for; the" purpose of co-operating with the crank handle A in order to force the lock ofthe gun into its forwardpositionin the event of the normal .forward movement of the lock being stopped by the jamming of an oversize car'- tridge in the cartridge chamber of thebarabove. I I

In the construction according .to Figure 1, D is a rotary shaft the inner end of which has-a handle D al-ranged in or close to the cock-pit A so that it can be operated by the 'Z'I'l. 'Inboth the constructions shown\the I auxiliary lever C isinthe position it occupies when it has been operated as stated gunner, and the outer end of this shaft car being arranged to pass clear of the mechain. an anti-clockwise direction when viewed from its outer end displaces the levers B, and" C together (owing to the co-operation of a. stop on the lever C withthe lever B) so. as to cause the lever B toco-o erate with the crank handle A", whilst angu ar movement of the said shaft in the reverse direction causes the lever C alone to move and co-operate with the said crank handle, this lever being returned to its original position by a spring C whenvthehandle D is released. In the caseof an aeroplane in which the whole or a part of each wing is made removable the shaft D would be made in two parts with a clutch betweenthem to permit separation to* occur when the wing or wing part is removed.

In the construction according to Figure 2 I the handle D is connected by a link D to a bell-crank lever D which is connected by a link D to a second bell-crank lever D" conlimited by a link D to the aforesaid auxiliary lever C, the operations being similar to those described-with reference to Figure 1. It will be understood that the plane of rotation of the levers D and D is at right anglesto that of D and B.

In cases in which onlythe cocking and loading lever B is em loyed the pin D of Figure 1 and the link a of Figure 2 would be connected to part ofthe said lever B.

What I claim and desire to secure by Let- 6 ters Patent of the United States is v 51 In am automatic gun, a cocking and loading lever for reproducing manually movements of the gun mechanism that occur duringroperation of the gun, an operating '10 handle remotely located with respect to the,

gun, and a rigid connection between said andle and the cocking and loadin lever.

2. In an automatic gun, a coc 'ng and loading lever for reproducing manually 15' movements of the gun mechanism that occur 'during operation of the'gun, an operating 4 handle and the cocking and loading lever.

3. In an automatic gun, a cocking and load- 20 ing lever for reproducing -manually movements of the gun mechanism that occur during operation of the gun, an auxiliary lever cooperating with the crank'handl oi the gun to force an over-size cartridge into the cartridge chamber of the gun barrel, and remotely located means for actuating said} auxiliary lever.
